Paralyzed man controls a robotic suit with a brain to walk

Researchers say their paralyzed patient (a tetraplegic man) was able to move his paralyzed arms and legs using a brain-controlled robotic suit.

A man paralysed in all four limbs has been able to walk while wearing an exoskeleton controlled by his brain signals. A 28-year-old man from France was paralyzed from the shoulders down. For two years he trained the computer algorithm to understand his thoughts, to make movements with the help of an exoskeleton. Scientists from the University of Grenoble in France, Biomedical Research Center Clinatec and the CEA Research Center have implanted an electronic device into a man’s head to receive signals from the brain’s sensorimotor cortex that control limb movement.

A brain implant collected human brain signals and translated them into the movements of a robotic exoskeleton. Today this paralyzed man can walk and stop using a robotic suit that he manages with his brain. This technology will help tetraplegic patients to drive computers using only own brain signals. People with disabilities will be able to drive wheelchairs or exoskeletons using brain activity instead of joysticks. This new technology will greatly increase their mobility.
